Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cotton yarn production equipment, specifically a cotton yarn shearing machine for cotton yarn production. Background Technology
[0002] In the cotton yarn production process, the cutting and winding stages are crucial. Traditional cotton yarn cutting methods mostly rely on manual operation of scissors. This method is not only inefficient and difficult to meet the needs of large-scale industrial production, but also causes workers to become fatigued due to repetitive labor during long periods of manual cutting, further increasing the probability of errors.
[0003] Furthermore, although existing cotton yarn shearing machines can cut cotton yarn, the yarn tends to spring back after being cut, requiring manual retraction. In addition, the traction process involves passing through a cutter, posing certain safety hazards during operation. Utility Model Content
[0004] To address the shortcomings mentioned in the background section, the present invention aims to provide a cotton yarn shearing machine for cotton yarn production, which solves the problems of low cutting efficiency, easy errors in manual operation, and safety hazards caused by the need for manual traction to prevent the cotton yarn from springing back after cutting.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A cotton yarn shearing machine for cotton yarn production includes a base. Guide rollers, a yarn cutting assembly, and a yarn take-up assembly are sequentially arranged on the base along the cotton yarn transmission direction. The yarn cutting assembly includes a fixed cutter, a movable cutter, and an electric telescopic rod for driving the movable cutter. The fixed cutter is fixedly installed on the base, and the movable cutter is connected to the output end of the electric telescopic rod via a movable seat. The fixed cutter and the movable cutter form a shearing engagement structure. The base also includes a clamping assembly, which includes a clamping member for clamping the cotton yarn end and a driving member for moving the clamping member in a direction parallel to the plane of the base.
[0007] More preferably, the clamping member includes: a slide block slidably connected to a base; bosses on both sides of the slide block, the bosses having guide holes; a compression rod slidably passing through the guide holes, the opposite ends of the two compression rods being fixedly connected to a clamping plate; and a compression spring sleeved on the outside of the compression rods, the two ends of the compression spring abutting against the bosses and the clamping plate respectively.
[0008] More preferably, the slide block is further provided with: an expansion rod hinged to the middle of the slide block; a spring seat fixed to the bottom end of the expansion rod; a spring plate connecting the spring seat and the slide block, the spring plate applying a preload force to the spring seat to cause the expansion rod to flip upward; and a limiting rod provided on the side wall of the boss, the limiting rod limiting its maximum flipping angle to a horizontal state when it contacts the expansion rod.
[0009] More preferably, the movable seat is provided with an L-shaped trigger plate. When the expansion rod is in a horizontal state, its free end extends between the two clamping plates and intersects with the movement trajectory of the trigger plate. When the trigger plate moves downward, it can push the expansion rod away from the clamping plate area.

[0024] like Figure 1-4 As shown, a cotton yarn shearing machine for cotton yarn production includes a base 1. A guide roller 2, a yarn cutting assembly, and a yarn take-up assembly are sequentially arranged on the base 1 along the cotton yarn transmission direction. The guide roller 2 guides the cotton yarn along a predetermined trajectory to ensure transmission stability. The yarn cutting assembly includes a fixed cutter 3, a movable cutter 4, and an electric telescopic rod 5. The fixed cutter 3 is fixed to the base 1. The movable cutter 4 is connected to the output end of the electric telescopic rod 5 via a movable seat 6, forming a shearing cooperation structure. The electric telescopic rod 5 drives the movable cutter 4 to achieve precise cutting.
[0025] The clamping assembly on the base 1 consists of a clamping component and a driving component. The slide 7 in the clamping component is slidably connected to the base 1 via a guide rod 17. Guide holes 23 are provided on the protrusions 8 on both sides of the slide 7. A compression rod 9 slides through the guide holes 23 and is connected to clamping plates 10 at both ends. A compression spring 11 is sleeved on the outside of the compression rod 9 and abuts against the protrusions 8 and clamping plates 10, thus achieving stable clamping of cotton yarn ends. Simultaneously, an expansion rod 12 is hinged to the middle of the slide 7, and its bottom end is connected to a spring seat 13. A spring plate 14 is provided between the spring seat 13 and the slide 7, providing a preload force to cause the expansion rod 12 to flip upwards. A limiting rod 15 on the side wall of the protrusion 8 limits the maximum flipping angle of the expansion rod 12 to a horizontal state. The free end of the horizontally positioned expansion rod 12 extends between the clamping plates 10 and intersects the movement trajectory of the L-shaped trigger plate 16 on the moving base 6.
[0026] The driving component includes guide rods 17, limiting blocks 18, screws 19, and a rotary motor 20 symmetrically arranged on the base 1. A slide 7 is fitted onto the guide rods 17. The screw 19 is rotatably connected between the two limiting blocks 18 and threadedly engaged with the slide 7. The rotary motor 20 drives the screw 19 via a coupling, causing the slide 7 to move along the guide rods 17, thus adjusting the position of the clamping component. The take-up assembly consists of symmetrical support frames 21 and detachable cotton yarn rolls 22, used to complete the take-up of the cut cotton yarn.
[0027] Workflow
[0028] Cutting preparation: At this time, the slide block 7 is in contact with the left limiting block 18, and the expansion rod 12 is located between the two clamping plates 10. The cotton yarn to be cut is passed through the guide roller 2. The guide roller 2 guides the cotton yarn along the predetermined trajectory, passes between the two clamping plates 10 and finally wraps around the cotton yarn roll roller 22. The electric telescopic rod 5 is in the initial position, and the movable cutter 4 and the fixed cutter 3 are in a separated state.
[0029] Cutting process: When it is necessary to cut cotton yarn, the electric telescopic rod 5 is activated. The output end of the electric telescopic rod 5 drives the moving seat 6 and the movable cutter 4 to move downwards. During the downward movement of the movable cutter 4, the L-shaped trigger plate 16 on the moving seat 6 moves downwards accordingly. When the trigger plate contacts the expansion rod 12 and pushes it away from the clamping plate 10 area, the two clamping plates 10, no longer supported by the expansion rod 12, quickly clamp the cotton yarn under the restoring force of the compression spring 11. At the same time, the movable cutter 4 continues to move downwards, cooperating with the fixed cutter 3 to cut the cotton yarn. The elastic force of the compression spring 11 makes the clamping plates 10 tightly clamp the yarn end, completing the clamping work of the yarn end. After the cutting is completed, the electric telescopic rod 5 resets, and the movable cutter 4 returns to its initial position.
[0030] Thread feeding: The drive unit is activated, and the rotary motor 20 drives the screw 19 to rotate. Under the limiting action of the guide rod 17, the slide 7 moves along the guide rod 17 towards the take-up assembly. During the movement, the cotton yarn end clamped by the clamping plate 10 is fed to the cotton yarn roll 22, preparing for the next take-up.
[0031] Take-up process: One end of the cut cotton yarn remains in the take-up assembly. The operator separates the two clamping plates 10, removes the yarn end, and under the restoring force of the spring plate 14, the expansion rod 12 re-enters between the two clamping plates 10 and is restricted to a horizontal state by the limiting rod 15. After removing the yarn end, the drive unit resets the slide block 7 and starts the take-up device (which can be driven by a motor, etc., to rotate the cotton yarn roll 22), winding the cut cotton yarn onto the cotton yarn roll 22 for take-up. When one roll is full, the cotton yarn roll 22 can be removed and replaced with a new roll to continue take-up.
[0032] Subsequent steps: Repeat the above steps to continue cutting and winding up the next section of cotton yarn. Throughout the process...
[0033] The entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
